antenna

I need to know whether the radio receivers that are highly sensitive, like having sensitivity less than 0.0224 micro volts for AM reception, encounter less fading than the others with less sensitivity? Which specification of a radio receiver is responsible for mitigating fading?

Hello everyone! General question: Is the telescopic antenna that came with the SDS200 radio have good range compared to a dipole? Backstory: My SDS200 is connected to a 50ft low-loss 50ohm cable connected to a dipole. I live in Eastern Kentucky ( Letcher County ) and range and reception is...

a few years ago i found my old Uniden Pro538w in a box in the basement, a buddy of mine had given men 2 102" whips, so i made a vertical dipole with them with the center mounted about 15ft up (where the coax connects) on my chimney... meh, i don't hear much, i just assumed CB was dead... then i...

Ok i have looked at tons of antennas and i am confused on a few different things for example a dual band and a tri band antenna if the tri band lets you cover more why would people even bother with a dual band is it because that if a antenna is programmed for a specific freqs it will pick up...

Good morning all. So I am bringing my SDS-100 up to Overgaard, AZ (Navajo County) which is extremely rural. The upgraded antenna (same size, just don't remember the manufacturer) works great to pick up the local stuff. However, things like Highway Patrol, the next city over, etc., which are...

so i built this linear loaded SWL antenna, a project i found on the swling website, which involved getting a a NooElec 9:1 balun in the middle of two 15ft pieces of romex bound at the ends in a way that it effectively makes a dipole with 45ft elements. this balun is not made for any kind of...

I am licensed but inexperienced. I bought a end-fed random wire antenna with the 9:1 balun. It held up poorly over the year. The wire is nearly torn apart, and of course I can replace that easily. But I am not sure it was ever working, and I don't know how to test the Balun to be sure. I...

I have used my small loop antenna (which has a main loop and a coupling loop that can be tuned using a variable capacitor) with an AM radio receiver to receive MW broadcasts. However, the small loop antenna which was made by me was not working properly but when I connected a ferrite rod loop...

So here is what i want to do, i have two antennas that i want to mount one is a discone and the other is a j pole and what i am trying to do is use a piece of pipe that is no bigger than 1' 3/8 in diameter and put the discone ontop of the pipe and midway's down attach the j pole i have already...

So i have been struggling to figure the answer out to this question for a while now. I bought the RTL-SDR kit and i don't know how to configure the antenna, videos on youtube have conflicting answers i see one person say use it one way and then another person in a different video says to use it...

I have a 30m EFHW resonant sloper antenna. I've completed tuning it using my RigExpert and have an excellent SWR at the antenna and the TXRX. I know that some common mode currents are present, so I have a CMC filter at the antenna and in the shack. I've attached an image showing the antenna...

Hi, I have this antenna https://rcw.co.za/wp-content/uploads/2022/05/5.-ANT-M-504-Mobile-Antennas-Highband.pdf. I'm listening to 150mghz range. I asked a car mechanic to install this antenna for me permanently in my car. It is on a mag mount. Before, I would stick the magnet on the side...

Hi All, I was playing around with a tigger tail for my HT. I found that the tigger tail gave me a nice enhancement for my HT up to 10 db. I have heard from others that it didn't make such a big difference. I would love to hear from others who tried this. You can see my experience in this...

Hi All, I recently conducted an experiment to determine the potential correlation between Standing Wave Ratio and tidal changes on a vertical antenna. My vertical 6BTV antenna is mounted on my dock over saltwater. While many factors influence antenna performance, the proximity to conductive...

I need to know which antenna among the monopole, dipole, and discone is best for HF reception?

Hi All, I have a 6BTV antenna mounted over salt water on my dock. I wanted to share a video about the installation, and a video about the real world performance of my vertical antenna. This antenna does not feel like a compromise to me. 73 All, Paul

Hello, all! I am new to Radio Reference and relatively new to scanners in general. This is my first post and I don't know if this question has already been answered by I figured I'd take a shot. I currently own a Uniden SDS100 and would like to get better reception inside my home. I live about...

My original antenna that come with vx8de broke, so I bought the new one on ebay, which was said to be original. Delivered from Italy. When the package arrived I noticed that antenna is lacking VS logo at its base. I emailed parts@yaesu.com, but I didn't get an answer on my question, instead they...

Good morning I’m looking for a NMO antenna for my Uniden bcd536 Is there something that’s a “cover all”? Currently have a https://www.gigaparts.com/comet-antennas-sbb-224nmo.html For a little tri band radio I’m looking At dropping. But would prefer something universal for this scanner

I need to know which type of antenna is best for scanning 3 MHz to 3 GHz signals using a RTL2832U SDR? What is the difference between using a telescopic and a discone antenna? Which is better?
